button to switch between trigger slopes. Use the Trigger LEVEL
knob to stabilize the trigger if required.
H Leave the trigger system triggered on the positive slope of the
waveform before proceeding to the next check.
H Press the Trigger SOURCE button to toggle it to CH 1.
4. Confirm that the trigger system is within sensitivity limits (full bandwidth):
a. Set the Horizontal Scale: Set the Horizontal SCALE to 200 ps.
b. Display the test signal:
H Set the generator frequency to full bandwidth as follows:
CSA7404B 3 GHz
TDS7704B 3 GHz
CSA7404B 3 GHz
TDS7404B 3 GHz
TDS7254B 2.5 GHz
TDS7154B 1.5 GHz
H Set the generator amplitude on screen as follows:
TDS7704B 7 divisions
CSA7404B 7 divisions
TDS7404B 7 divisions
TDS7254B 5 divisions
TDS7154B 5 divisions
H Now fine adjust the generator output until the CH 1 Amplitude
readout indicates the amplitude is as follows (Readout may
fluctuate):
TDS7704B 750 mV
CSA7404B 750 mV
TDS7404B 750 mV
TDS7254B 500 mV
TDS7154B 500 mV
H Disconnect the cable at CH 1 and reconnect it to CH 1 through a 5X
attenuator. Check that a stable trigger is obtained.
c. Repeat step 2, substep b for the full bandwidth selected.
d. Display the test signal (delay trigger at 1.5 GHz):
H Set the generator frequency as follows:
CSA7404B 1.5 GHz
